# shape_pie
|
||
|
|
|
||
|
|
Returns shape points and triangle indexes of a pie (circular sector) shape. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.
|
||
|
|
|
||
|
|
## Parameters
|
||
|
|
|
||
|
|
- `radius` : The radius of the circle.
|
||
|
|
- `angles` : A 2 element vector which defines the central angle. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
|
||
|
|
- `$fa`, `$fs`, `$fn` : Check [the circle module](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_the_2D_Subsystem#circle) for more details.
